Jorma Ludwik Kaukonen, Jr. (born December 23, 1940) is an American blues, folk, and rock guitarist, best known for his work with Jefferson Airplane and Hot Tuna. Born in Washington, D. C. , the son of Beatrice Love and Jorma Ludwig Kaukonen, Jorma Kaukonen had Finnish paternal grandparents and Russian Jewish ancestry on his mother's side.

Kaukonen was a founding member of the popular psychedelic San Francisco-based band Jefferson Airplane. In 1962 Kaukonen moved to the San Francisco Bay Area and enrolled at Santa Clara University.

During this time he taught guitar lessons at Benner Music Company in San Jose. As a self-described blues purist, Kaukonen never had any ambition to play in a rock band.

He played as a solo act in coffee houses and can be heard accompanying a young Janis Joplin on acoustic guitar on an historic 1964 recording (known as "The Typewriter Tapes" because of the obtrusive sound of Kaukonen's first wife, Margareta, typing in the background). Invited to attend a Jefferson Airplane rehearsal by founding member Paul Kantner, Kaukonen found his imagination excited by the arsenal of effects available to electric guitar and later said, "I was sucked in by technology.

" In 1969–70, Kaukonen and Jack Casady formed Hot Tuna, a spinoff group that allowed them to play as long as they liked. An early incarnation of Hot Tuna included Jefferson Airplane vocalist Marty Balin and featured Joey Covington on drums and vocals.

This grouping came to an end after an unsuccessful recording jaunt to Jamaica, the sessions of which have never been released. In 1974, Kaukonen recorded the first and most successful of several solo albums, Quah, together with Tom Hobson.

Produced by Jack Casady, and featuring (somewhat surprisingly) string overdubs on some tracks, this album contained some of Kaukonen's most deft fingerpicking work, especially on "Hamar Promenade", "Blue Prelude", "Genesis" and " Flying Clouds". The curious picture that adorns Quah's cover is today on display at Donkey Coffee and Espresso, a coffee shop in Athens, Ohio.

Kaukonen toured vigorously throughout the 1970s in both the United States and Europe, but with Hot Tuna's break up in 1978, the first phase of the band's career ended. Casady left to form the new wave band SVT, while Kaukonen released his second solo album, Jorma, a mix of electric guitar and acoustic fingerstyle in 1979.

Meanwhile, he had formed the band "Vital Parts.
